8.2.1 Installing AquaVent Wellhead Batteries

Note:

After retrieving the settings in Levelogger Software, If the Wellhead batteries have drained to 20% charge or lower, a warning message will appear to replace the batteries.

Each Wellhead uses four (4) 1.5V AA replaceable lithium batteries. To install the batteries, follow the steps below:

  1. Unscrew the top of the Wellhead to access the battery compartment.
  2. Carefully remove the battery holder from the compartment.
  3. Install the four batteries in the holder. Ensure proper polarity when placing the batteries, paying attention to the positive {+} and negative {-} symbols etched in the holder.
  4. Slide the battery holder back into the compartment. Ensure proper alignment; the spring contacts in the housing should be lined up with the protruding contacts on the bottom of the battery holder.
  5. Screw the top cap firmly back onto the Wellhead.
  6. After replacing the batteries, to reset the battery indicator in the Levelogger Software, use the Diagnostic Utility (see Section 10.6).
